Identity Verification Standards in Welfare Programs
We study the impact of reforms that introduced more stringent, biometric ID requirements into India’s largest social protection program, using large-scale randomized and natural experiments. Corruption fell but with substantial costs to legitimate beneficiaries, 1.5–2 million of whom lost access to benefits at some point during the reforms. At the same time, adverse effects appear to have been driven primarily by decisions about the way the trans…
Factorial Designs, Model Selection, and (Incorrect) Inference in Randomized Experiments
Factorial designs are widely used to study multiple treatments in one experiment. Although t-tests using a fully saturated “long” model provide valid inferences, “short” model t-tests (that ignore interactions) yield higher power if interactions are zero, but incorrect inferences otherwise. Of 27 factorial experiments published in top-five journals (2007–2017), nineteen use the short model. After including interactions, more than half of their re…
Personnel Management and School Productivity
This paper uses new data to study school management and productivity in India. We report five main results. First, management quality in public schools is low, and ∼2 standard deviations below high-income countries with comparable data. Second, private schools have higher management quality, driven by much stronger people management. Third, people management quality is correlated with independent measures of teaching practice, as well as school p…
Augmenting State Capacity for Child Development
Two Indias
We visited 1519 villages across 19 Indian states in 2009 to (a) count all health care providers and (b) elicit their quality as measured through tests of medical knowledge. We document three main findings. First, 75% of villages have at least one health care provider and 64% of care is sought in villages with 3 or more providers. Most providers are in the private sector (86%) and, within the private sector, the majority are 'informal providers' w…
Inputs, Incentives, and Complementarities in Education
We present results from a large-scale randomized experiment across 350 schools in Tanzania that studied the impact of providing schools with (i) unconditional grants, (ii) teacher incentives based on student performance, and (iii) both of the above. After two years, we find (i) no impact on student test scores from providing school grants, (ii) some evidence of positive effects from teacher incentives, and (iii) significant positive effects from …
Disrupting Education? Experimental Evidence on Technology-Aided Instruction in India
We study the impact of a personalized technology-aided after-school instruction program in middle-school grades in urban India using a lottery that provided winners with free access to the program. Lottery winners scored 0.37 σ higher in math and 0.23 σ higher in Hindi over just a 4.5-month period. IV estimates suggest that attending the program for 90 days would increase math and Hindi test scores by 0.6 σ and 0.39 σ respectively. We find simila…
Cycling to School
We study the impact of an innovative program in the Indian state of Bihar that aimed to reduce the gender gap in secondary school enrollment by providing girls who continued to secondary school with a bicycle that would improve access to school. Using data from a large representative household survey, we employ a triple difference approach (using boys and the neighboring state of Jharkhand as comparison groups) and find that being in a cohort tha…
Experimentation at Scale
This paper makes the case for greater use of randomized experiments "at scale." We review various critiques of experimental program evaluation in developing countries, and discuss how experimenting at scale along three specific dimensions-the size of the sampling frame, the number of units treated, and the size of the unit of randomization- can help alleviate the concerns raised. We find that program-evaluation randomized controlled trials publis…
Quality and Accountability in Health Care Delivery
We present unique audit-study evidence on health care quality in rural India, and find that most private providers lacked medical qualifications, but completed more checklist items than public providers and recommended correct treatments equally often. Among doctors with public and private practices, all quality metrics were higher in their private clinics. Market prices are positively correlated with checklist completion and correct treatment, b…
Building State Capacity
Antipoverty programs in developing countries are often difficult to implement; in particular, many governments lack the capacity to deliver payments securely to targeted beneficiaries. We evaluate the impact of biometrically authenticated payments infrastructure (“Smartcards”) on beneficiaries of employment (NREGS) and pen sion (SSP) programs in the Indian state of Andhra Pradesh, using a large-scale experiment that randomized the rollout of Smar…
The Aggregate Effect of School Choice
We present experimental evidence on the impact of a school choice program in the Indian state of Andhra Pradesh that provided students with a voucher to finance attending a private school of their choice. The study design featured a unique two-stage lottery-based allocation of vouchers that created both student-level and market-level experiments, which allows us to study the individual and the aggregate effects of school choice (including spillov…
Teacher Performance Pay
We present results from a randomized evaluation of a teacher performance pay program implemented across a large representative sample of government-run rural primary schools in the Indian state of Andhra Pradesh. At the end of 2 years of the program, students in incentive schools performed significantly better than those in control schools by 0.27 and 0.17 standard deviations in math and language tests, respectively. We find no evidence of any ad…
The Impact of Diagnostic Feedback to Teachers on Student Learning
We present experimental evidence on the impact of a programme that provided low-stakes diagnostic tests and feedback to teachers, and low-stakes monitoring of classroom processes across a representative set of schools in the Indian state of Andhra Pradesh. We find teachers in treatment schools exerting more effort when observed in the classroom but students in these schools do no better on independently-administered tests than students in schools…
Missing in Action
In this paper, we report results from surveys in which enumerators made unannounced visits to primary schools and health clinics in Bangladesh, Ecuador, India, Indonesia, Peru and Uganda and recorded whether they found teachers and health workers in the facilities. Averaging across the countries, about 19 percent of teachers and 35 percent of health workers were absent. The survey focused on whether providers were present in their facilities, but…
